AI Technical Summary

Problems solved by technology

The network cannot monitor these services because there is no obvious location and presence information between the network and the client terminal
[0005] It can be seen that in the co-ps technology, because the state information of each connection needs to be kept in the middle node of the network, there is usually a problem of scalability, and it is impossible to provide a finer-grained quality of service (Quality of Service, hereinafter referred to as QoS) guarantee, otherwise the state information of intermediate nodes will be too much; in the cl-ps method, since there is no process of establishing a connection, it is impossible to predict the resource conditions of the network and the destination terminal, and it is difficult to strictly guarantee QoS

Embodiment Construction

[0021] Such as figure 1 As shown, taking the packet switching network of the present invention to provide destination-based IP user data packet / flow (abbreviation: IP packet / flow) transmission service as an example, two working modes are given: mode 1 and mode 2. Mode 1 works in the Best effort mode, and IP packets / flows do not need QoS guarantee; Mode 2 works under the control of the quality of service policy (hereinafter referred to as QoS Police), and IP packets / flows need QoS guarantees.

[0022] Such as figure 2 As shown, the load information of the IP packet / flow that the user sends generally can own source and purpose IP address (network address character), when a co-ps or cl-ps load that contains high-level service information arrives at the packet exchange of the present invention At the network entrance, the packet switching network generates the packet header of the packet switching network of the present invention according to the IP packet / flow load information,...

Abstract

The packet switching method facing connection or connectionless network comprises: building packet switching network faced connection or connectionless, allocating global fixed address to the node on packet switching network; on the entry node of the network, generating packet head according to load information of user data packet / flow, transmitting the packet head in the network or routing the user data packet / flow; on the exit node, separating the packet head to recovery the load information. This invention has advances in service quality and security and expansibility.

Description

technical field [0001] The invention relates to a network packet switching method, and in particular to a connection-oriented and connectionless network packet switching method. Background technique [0002] Network switching technologies currently include three categories: connection-oriented circuit switching (Connection Oriented Circuit Switching, hereinafter referred to as co-cs) technology, connection-oriented packet switching (Connection Oriented Packet Switching, hereinafter referred to as co-ps) technology and connectionless packet switching Switching (Connectionless packet switching, hereinafter referred to as cl-ps) technology. Current typical co-ps technologies include Asynchronous Transfer Mode (Asynchronous Transfer Mode, hereinafter referred to as ATM) and X.25, and typical cl-ps technologies include IP and Ethernet (Ethernet). Recommendations G.805 and G.809 of the International Telecommunication Union-Telecommunication standardization sector (ITU-T) respecti...
